Abstract
- The effect of high-pressure torsion on the microstructure was studied in high-nitrogen austenitic steels with different vanadium content: Fe-23Cr-19Mn-0.2C-0.5N, Fe-19Cr-21Mn-1.3V-0.3C-0.8N and Fe-18Cr-23Mn-2.6V-0.3C-0.8N, wt %. Independently of the chemical composition of steels, high-pressure torsion causes the refinement of the microstructure of high-nitrogen steels due to the formation of a high density of twin boundaries, dislocations and shear bands. Vanadium-alloying promotes the change of dominating deformation mechanism from planar slip and twinning (vanadium-free steel) to slip with pronounced shear band formation (vanadium-alloyed steels) under high-pressure torsion. Increase in vanadium concentration in steels provides more misoriented microstructure in comparison with V-free steel. [ABSTRACT FROM AUTHOR]
